UFC President Dana White announced the news on Thursday,
according to a report from UFC broadcast partner Fox Sports. The
promotion is now reportedly seeking a replacement for the injured
“Uncle Creepy.”

UFC Fight Night 37 takes place March 8 at the O2 Arena in London
and is headlined by a light heavyweight meeting between former
title challenger Alexander
Gustafsson and hard-hitting Englishman Jimi Manuwa.
The event streams live on UFC Fight Pass and will also see Ross
Pearson collide with Melvin
Guillard in a lightweight rematch.

McCall, 29, halted a two-fight skid in his most recent outing, when
he outpointed game Brazilian Iliarde
Santos this past August at UFC 163. A 17-fight pro, the former
Tachi Palace Fights champion was also forced to withdraw from a
planned Dec. 14 clash with Scott
Jorgensen due to injury.

Pickett, 35, has suffered defeats in two of his last three outings,
prompting the longtime 135-pound talent to make the move to
flyweight. “One Punch” last competed on Aug. 17, suffering a
second-round submission defeat to Michael
McDonald in a “Fight of the Night” worthy effort at UFC Fight
Night 26.
